11 Claims.

This invention relates to improvements in jacquards and more p-articularlyito the mounting for the gudgeons of the jacquard cylinders.

In my prior Patent No. 2,045,946 I show a bearing for the jacquard cylinder gudgeon comprising a sleeve around the gud'geon removable fromthe latter and cooperating with an anti-friction bearing held in a fixed part of the jacquard structure. It is essential to preserve horizontal alignment of the needle holes in the jacquard cylinder so that they will register correctly with the needles controlling the warp lifting jacks. It is an important object of my present invention to modify the bearing set forth in my aforesaid patent by adding a positioning screw or the like for end adjustment of the cylinder so constructed as to permit lubricating of theinterior of the bearing.

It is a further object of my present invention to provide a wear resisting plug between the end of the gud'geon and the adjusting screw so located as to be lubricated when grease or oil is introduced through the adjusting screw. This plug may conveniently be carried by an extension of the sleeve which surrounds the cylinder gudgeon as set forth in the aforesaid patent and is removable so'that when worn it can be renewed. The plug prevents direct contact between the adjusting screw and the cylinder gudgeon to pre- I vent wear of the latter, and the lubrication to be described hereinafter also prevents Wear of the plug and screw.

With these and other objects in view which will appear as the description proceeds, my'invention resides in the combination and arrangement of parts hereinafter described and set forth.

In the accompanying drawing, whereina convenient embodiment of my invention is set forth,

Fig. 1 is a side elevation of a portion of the jacquard incorporating my invention,

Fig. 2 is an end elevation on an enlarged scale looking in the direction of arrow 2, Fig. 1,

Fig. 3 is a detailed vertical section on line 3-3 of Fig. 2, and N Fig. 4 isa detailed longitudinal section through the adjusting screw on line 4-4, Fig. 3.

Referring to the drawing, I have shown the jacquard cylinder l0 having a gudgeon II on each end thereof. Horizontal pins l2 at the ends of the cylinders cooperate with positioning hammers l3 urged downwardly by springs l4, one of which is shown in Fig. 3, ,to assure correct angular positionof the ,;cylinder, around its axis when prcsentedto the needles 'not' shown of the jacquard. v

The structure at each end of the jacquard is substantially the same as that shown in Fig. 3 and it is thought a description of one end, that is the right end, as shown in Fig. -1 will sul'l'ice for both ends. a Y

The gudgeon l I is surrounded by a sleeve secured to the gudgeon by a collar 2| and set screw 22. The latter extends throughthe sleeve to hold it against substantial horizontal misplacement .alongfthe gud'geon. The sleeve extends into, an anti-friction roller bearing Rcomprising rollers enclosedin a surrounding shell 3| and lying around the hardened sleeve 20. The bearing R has a chamber 33 to receive a lubricant for the rollers 30.

The bearing R is held by set screw 31 carried by. a bearing bracket 36. The upper part of the latter vIis secured to fixed structure 40 by means of a bolt, while the vertical position of the bracket, is determined by an adjusting screw 42 For a parts not directly concerned with the subject matter of my present'invention, reference may be hadto the patent mentioned.

My present'invention relates more particularly to an end adjustment for the jacquard'cylinder l0 and in carrying my invention into effect I provide horizontal adjusting screws 50 and 5| located respectively at the right and left, endof thecylinder as viewed in Fig. 1. Each of these screws and the parts associated therewith are substantially the same, andI will describe the invention as applied to the right end of the jacquard with the understanding that it applies to the structure at theleft end of the jacquard also.

The screw 50 is threaded into bearing R. and is held in its horizontal position with respect to the bearing R by means of a lock nut 52. The previously described set screw 31 determines the horizontal position of the bearing R, hence the screw 50 will be held fixedly in adjusted position.

by the nut' 52. Inorder that the screw 50 may be turned it is provided with ahead 53 accessible from'the outer side of the jacquard.

.The previously described sleeve .20 is extended.

as at 55 to overhang the end 56 of the gudgeon I i. Fitted into the overhanging end of the sleeve is a wear resisting plug 6B formed of a wear resisting material, such as bronze, and shown herein as having a head 6i of a diameter somewhat larger than the internal diameter of the sleeve 20 so that it can engage the end of the sleeve. The inner end of the screw 5!! bears against the vertical face 62 on the outer part of the plug 6t and it is by this relation that the adjusting force is transmitted longitudinally from the screw 50 to the sleeve 20.

In order that the chamber 33 may be filled with lubricant the screw 50 is' provided with a bore 65 closed at its outer end by a fitting 66. The fitting has a bore l0 closed at its inner end by a ball ll urged against a seat 12 on the interior of the fitting by a spring 13 held" inplace by a web it of the fitting perforated at 15 for passage of grease or the like. Lubricant may be introduced. under pressure through the bore 65 against the plug 60, the lubricant being squeezed laterally through the small clearance space between the screw 56.v and the plug 6!] and into the chamber 33, thus lubricating the plug.

Since sleeve. Zillis fastened to the gudgeon II by set screw 22, motion of the adjusting screw 56 to the left, for instance as viewed in Fig. 3, will move the cylinder iii to the left by a force transmitted. through the plug 550 and the sleeve 20. While I have shown the particular form of plug in association with the extended end of the sleeve 2.6 I do not wish necessarily to be limited to that form of plug since it is sufficient if the latter lie between the screw 50 and the gudgeon of the cylinder and preferably though not necessarily is held in position by the sleeve 20.

Fromthe foregoing it will be seen that I have provided simple means for adjusting the position of the jacquard cylinder in the direction of its axis and that this adjustment is effected by means of a screw or the like through which lubricant can be introduced into the chamber 33. It will also be seen that the shell can conveniently be extended to provide means for holding the wear plug 60in position for engagement with the adjusting screw 50. Also, the fact that the lubricant which is introduced into chamber 33 is squeezed out through the space between the end of the screw 50 and the plug insures proper lubrication of the latter.

Having thus described my invention it will be seen that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is:
